emm109.1 (emm-cluster E4) subtype determining sequence. Identity to bases 31-180 (encodes mature N-terminus) and ungapped identity or near-identity to complete 180 base sequence defines this subtype. emm109.1 obtained from year 2004 external quality assurance GAS strain 17. CDC designation = 313-04(T6,sof109), obtained from Dr. Androulla Efstratiou, Respiratory and Systemic Infection Laboratory, London. Identical in 150 base subtype-defining region to accession AJ549818 (however this one differs by single base del within putative signal sequence-encoding region). emm109.1.sds Length: 180 May 23, 2007 14:12 Type: N Check: 2487 .. 1 GGCTTTGCAA GCCAAACAGA AGTTAAGGCG GAGTCTCCAA AAAGTGCTGA 51 TAACTTAGCG AAGGAATACA ACACATTGCT TACTGAAAAT GAGAAACTCA 101 GAGAAGAGCT CCAACAGTAT TATGCATTAA TTGATGCTAA AGAAGAAGAA 151 CCTAGGTATA AAGCATTGAG AGGCGAAAAT
